What is the Best Glock .45 ACP? Glock 21 vs. Glock 41

The most popular round behind the 9mm Luger is the .45 ACP for both law enforcement officers (F.B.I., Sheriff Deputy, State Police, etc…) and civilians alike.

The majority of all Americans prefer the 9mm Luger at the moment, but I tend to believe that gun choice is cyclical. However, The .45 ACP is carried by millions of Americans for a reason.

The evolution of 111 (M1911 pistol) years has led us past the world-famous M1911, to guns like the Glock 21, Glock 41, or the Springfield Loaded. All three guns are incredible, but not all 3 guns are equal to each other.

We are fortunate to have such a large audience for Glock blogs that I wanted to give my 2-cents on Which Glock .45 ACP pistol that I’d carry and why.

Glock 21 vs. Glock 21SF

The Glock 21 comes in 2 different models (Glock 21 Gen 4 & Glock 21SF) with slight differences between the 2. The Glock 21 Short Frame (SF) has all the same specs and the original Glock 21, except for the Length of Pull (LOP).

The Glock 21SF has a shorter LOP to allow shooters with smaller hands to get a better grip on a full-sized Glock .45 ACP caliber.

The Glock 21SF was originally meant as a duty weapon for smaller officers who prefer a heavier bullet over the 9mm.

The biggest difference between the 2 guns is the width of the grip from the trigger to the rear of the grip. The heel of the grip on the G21SF is 4mm shorter than the G21 and 2.5mm shorter in the grip from the trigger to backstrap.

The big takeaway from the SF model is you can grip the pistol better, offering more control of recoil, which will improve your accuracy for follow-up shots.

Is the Glock 21 Discontinued?

From everything I can tell, the Glock 21 has been discontinued by Glock, along with the Glock 20, 29, and G30 for the original models, but not the SF models.

I think it became an issue where many shooters were having too many problems with the bulkier grip of the original G21. My 2 closest friends are almost twice the size of me and still prefer to shoot the Glock SF models over the standard Glocks in the larger calibers.

Where Can I Buy a Glock 21 Gen 4 Holster?

We The People Holsters is an American company that we love to support because all their products are American-made and they’re actively supportive of the military and LEO communities. As you can see from the printing on the holster, they have some really awesome-looking holsters that come with a lifetime warranty for any defects or manufacturing issues.

This specific holster is used as an Inside waistband holster (IWB) to provide concealment and security. The Kydex material is 100% waterproof, can handle dings, scratches, and drops from about any distance without destroying the holster.

This is the durability that is needed to compete with the big dogs in weapon accessories and We The People Holsters does it well enough to earn our support.

Where Can I Buy a Glock 21SF Holster?

Since the Glock 21SF is more of an LEO pistol, the holster you use should have a respectable retention system to avoid getting your gun ripped out of the holster by an assailant. According to the Bureau of Justice Assistance (BJA) in a national survey of police officers, the biggest concern for police is getting shot with their own gun.

If I were still a police officer, my first choice at a holster would be a Safariland Self Locking System (SLS) design with a Level 2 or Level 3 retention system. The durability, reliability, and practicality of Safariland products are known throughout the LEO and military communities.

The Safariland SLS Tactical Holster provides an incredibly smooth single-motion draw and can’t be pulled out from someone reaching for your pistol. The Safariland SLS Tactical holster provides extra gun security by preventing the hood from being released unless the gun is pushed down and rotated forward at the same time (simultaneously).

If someone tries to pull the holster out and up, the holster actually becomes more secure and locked in, preventing any mishaps while under stress. I suggest LEOs practice with different retention systems to find out which is best for them. Security is important, but being able to quickly draw your pistol is vital to the survival of our officers.

Is the Glock 21 Legal For Civilian Use?

Yes, although the Glock 21 SF was originally meant for LEOs, the Glock 21 is legal for any us to buy from authorized dealers, such as Guns.com, Kentucky Gun Company, Primary Arms, and Sportsman’s Warehouse. Since Glock has discontinued the original Gen 4 G21, it’s difficult to find and most LEOs and civilian shooters are moving toward the Glock 41.

Features

  • Rough Textured Grip (RTF)– The RTF added to the Gen 4 enhances the grip traction for inclement weather, such as rain, snow, humidity, cold, etc.
  • Dual Recoil Spring Assembly- The dual recoil spring is designed to reduce the felt recoil from the operation and increase the lifespan of the gun
  • Enlarged Reversible Mag Catch- The mag catch on the G21 & G41 is large enough for everyone to comfortably press without interfering with the operation of the gun.
  • Interchangeable Backstrap System- The small backstrap is the stock size shipped to you. The medium backstrap to add 8/100 of an inch from the back of the grip to the trigger.  For the largest hands, you can add the large, which gives you 16/100 of an inch.

Glock 41

The Glock 41 is now the only .45 ACP full-size Glock that’s in production for a very good reason; it’s better than the 21. Everything about the Glock 41 was meant as an upgrade from the G21.

The G41 features the same magazine capacity as the standard 13+1 round mag in the G21, but is lighter and has a thinner slide width for a better tactical advantage when drawing from a holster.

The Glock 41 is viewed as a competition holster, especially with its success in competitions, such as the International Practical Shooting Confederation (IPSC) and the United States Practical Shooting Association (USPSA). However, it’s a great option for open-carry and home defense purposes as well as competition.

For example, if you load some Sig Sauer 230 Gr SIG V-Crown Jacketed Hollow Points rounds in your G41, you’d stop any assailant in their tracks with one hit anywhere center mass. The longer barrel and slide length give you a longer line of sight and better recoil control for the heavier round.

  • The G41 also reduced the height of the G21 to further improve the tactical advantage of drawing from a holster

Where Can I Buy a Glock 41 Holster?

Depending on how much money you’d like to spend, there are different options for you to choose from.

However, I’ve found the We The People Holsters are more affordable, have a more unique level of customization in their aesthetics, and are durable enough for competition and carry.

Glock 41 MOS

I’ve never really thought about how practical it was to buy the MOS model for Glocks over the standard issues until I got more into optics and other weapon attachments, such as lights and lasers.

The MOS version of any Glock is going to be more expensive than any standard version because they come drilled, tapped, and ready to install optics without interfering with the line of sight or ergonomics of the pistol.

Anytime you get a gun that has the potential of adding an optic, light, or laser, you need to be sure the attachments will fit inside your holster.

With the Safariland 6390RDS Automatic Locking System (ALS) holster, you can be confident and comfortable knowing there is adequate room for the pistol and any micro-optic that is designed to fit on the Glock 41. The belt-loop has a unique feature that allows the pistol to be carried lower than normal to add more concealment and to protect the gun more.

Glock 41 Problems?

Anytime people talk about problems with a Glock, it immediately piques my interest because of the famous reliability and durability of Glock pistols.

I think most problems with the Glock 41 relates to the Gen 4 models specifically rather than the G41 model.

However, there are enough complaints about 3 specific features of the Glock 41 that I think everyone should know.

  1. Some ammo doesn’t feed properly in the Glock 41 versus others. I’ve read a lot of complaints about target ammo not feeding properly versus HP self-defense ammo. My suggestion is to clean your Glock 41 more than you do your 9mm Glocks. FOr whatever reason, I’ve found that my heavier pistols (.45 ACP, 10mm) have to be cleaned more than my 9mm pistols and this will cause failure to feed problems if the slide is caught on carbon or dirt.
  2. Accuracy issues out of the box. I’ve seen a lot of issues with brand new Glock 41’s that are shooting poorly right out of the box. I’ve had this issue with many pistols in the past and it’s due to shipping (most of the time). If the shipping company is rough on the load, you can see your sights being thrown off or loosened upon arrival. One of the most underestimated tools in my bag is the Wheeler Armorer’s  Handgun Sight Tool. You can easily ensure your handgun sights are on target with this tool and it works on any handgun, so you can use it for decades on your whole collection, well worth the cost!
  3. Trigger Pull Weight inconsistencies are a common complaint I see from Glock 41 owners. There can be many reasons for this issue, but mostly it’s a manufacturing defect or lubrication issue. Sometimes the internal parts of a pistol take some time to break in to loosen up to the proper specs. However, the best thing about Glock is there are many different aftermarket accessories you can add to fix this problem with ease. The GHOST Ultimate 3.5 lbs Drop-In Trigger is a great choice for only $23.99.
