I have been entertaining the idea of buying a 45 GAP model for over a year now, but have been putting it off. If I do buy one it will be around November or so, hopefully when the 4th gen models are out. I carry a G23. I'm not saying the GAP would replace the 23 for carry, simply because I love that pistol so much, but it might be nice to have as an option. I know that I could get away with carrying a full size 37 (I'm 6 foot 180 lbs, carry IWB), but have the most confidence in the 38 size for concealment. Since I know I can CC both, is there a major performance drop off from the 38 going down from the 37? I would plan on using 230 grain Ranger T if I could find it, and I've seen chrono numbers for it from a 38 in the 870 fps range. Would I be best off buying a 37 and hiding the 1/2 inch of extra grip for the better ballistics, or are the ballistics from the 38 nearly identical, or so close to the 37 that the difference is negligible? Also, will the 38 fit into existing holsters made for the 23? I use a Nick Mathews #1. I'm sure Nick could answer that, but was curious if anyone has tried it themselves.

THANKS!

I am not familiar with Nick Mathews holsters, but most holsters for the 9mm or .40 Glocks will not work due to the slightly thicker slide on the .45 GAP models.

I own and have carried all three GAP models. The 38 is almost as easy to conceal as the 39, carries 2 more rounds, and is easier to shoot with some precision. The longer grip on the 37 can be a PITA to conceal with some clothing. The longer sight radius of the 37, in theory, should allow for more precise shot placement but theory does not seem true with most shooters. Since acquiring the 38, I so rarely carry the 37 that my 14 year old grandson seems to have adopted it! In fact, he will be using it for our four-day course at Front Sight in a couple weeks.

I can't speak for the 38 (never fired one), but the 37 is a sweet shooter. I also have 180g Ranger T's for my G37.

CCW - the G38 will be easier.

Just buy G-37 mags for your "extras". Those mags are 10 rounders and will work in either G37 or G38. When you get around to owning both, all your magazines will work.

Has anyone done a side by side comparison between the GAP and the 40 round? Other than a bigger diameter bullet, what types of advantages will I get that make losing 5 rounds ok? Just curious. I've heard the GAP is a soft, accurate shooter. Looking for someone that has experience shooting both.

Well, that's me. I started my Glockism with a 35 a year and a half ago, shot it some in USPSA competition. Have owned 2 23s, a gen.2 and a 3, and really liked the latter. Got the urge for something different and bought a 38 with Pearce +1 extenders.

Subsequently bought a pair of 37s that I shoot in USPSA Production class. I chose the 37 because it makes slightly larger holes in the targets, and I need ALL of those I can get, and because the recoil is still very manageable after a couple-hundred rounds in a day.

The recoil of the GAP is definitely slower, hence it feels 'softer'. The .40's (and the 357SIG's, too) recoil is much quicker, snappier. All half-dozen of my .40s and GAPs were/are accurate guns, more so than my 357SIG model 32.

Some believe that the bigger holes made by .45-cal. expanded bullets are better at disabling badguys, but I have no experience at that. Here are examples of expanded Gold Dots; .40 left, .45 center, .357SIG,right.

I think it comes down to which side of the bigger-and-slower v. smaller-and-faster controversy you believe in. For a while I carried 'bigger'; now I carry 'smaller'.

If recoil bothers you more than it bothers the average person, buy a .45GAP in the size that feels best in YOUR hands. If you carry that pistol for PD, buy a few boxes of 185g. Speer Gold Dot factory loads and be VERY happy with your personal-protection firearm. :supergrin:

I hope I'm not violating forum rules by stating that I have the above-pictured 38 for sale; e-mail me at jeffreybehr(at)cox(dot)net if you're at all interested.

Thanks Jeff. That was informative. I like the idea of the 45 round, but I'm not sure where I fall in the big/slow, lighter/faster category. My G23 has a lot of mileage on it. It would be a hard separation. I might have to research this a bit more closely. The expanded diameter of the 40 and 45 rounds are nearly identical. Do you recall the penetration depth of each, or the velocity of each? I assume the 185 GAP was in the 1090fps ball park?
Thanks!

I have a G23 with a KKN 357 Sig barrel (very accurate) and a lone wolf 9mm conversion barrel (not very good). You'd say, why bother with anything else. Well I found that I could do without the 'snappy' recoil of the 40/357. While I was able to make some accurate, reliable reloads I never enjoyed shooting the pistol.
Came across a 'used' G38. I'm used to the 'push' of the 45 - have several 1911s on the shelf. The GAP shot sooo well I added a G39 to my shelf and when I get my butt in gear a G37 is in the cards.
Read thru this section and you will find numerous posts with the general statement that: 'my GAP is the best shooting pistol I have'. I think that Glock wants 'their' caliber to be respected. My speculation, they (Glock) is putting an extra something into the G37/38/39 pistols to make them as good as possible.

dave - no one can argue with a 45 hole

Glock 37 in Gen 4 or a 38!

I found them at the Gun show, a little pricey but at least they had them.

The expanded diameter of the 40 and 45 rounds are nearly identical.

I just corrected the labeling, but they're still very close in diameter.

All the tested bullets were shot into a series of 4 1-gallon waterjugs; all entered the 4th jug and did not exit. The 165g. 40's 10-foot velocity was
1094FPS; I can't find my notes on which GAP reload I tested, but the velocity of the 185 certainly was somewhere in the 1nnnFPS range.

A 185 grain or 200 grain at ~1000 fps is definitely going to hit harder than a 165 @ 1100 or 180 @1000. This may be something to think about.

1. 27% greater frontal area.
2. Less "sharp" recoil and sound.
3. About 40% less chamber pressure = more reloads on brass.

Just have to shop around a bit - I just got 23 boxes of 200 gr Lawman from AIM Surplus for $16 apiece! Hopefully they'll start stocking it regularly.

I bought the G 37 initially to get feel for the round. Now that I have about 1k rds through it, I am looking for a G 38 to put in the CCW rotation. I may move replace my 21sf and 36 with a 37 and a 38.

Time will tell....

I have a G38 that is my daily carry in a Blade-Tech Nano holster. It's much nicer to carry IWB than my G17 (same size as a G37) is in the same Blade-Tech Nano holster.

37 Gen. IV with a 38 lower!

.45 GAP is a sweet shooter!

I will wait about one year I hope and get one!

Best carry and I just want one.:rofl:

I can provide some chrono info from my 38: (average of 5 shots)
45 GAP Winchester Silvertip 185 gr. @ 908 fps (338# KE)
45 GAP Winchester Ranger T 230 gr. @ 788 fps (317# KE)

You mentioned the 23, I've got 27 data for the comparable 40 S&W loads as 45 GAP listed above.

Model 27:
40 S&W Winchester Silvertip 155 gr. @ 1,090 fps (409# KE)
40 S&W Winchester Ranger T 165 gr. @ 1,116 fps (456# KE)

Wow, the GAP loads are slow as hell. 788fps for a 230 grain round is very slow considering Winchester specs that round at 905fps from a 5 inch tube. I'd expect 850 fps from a 4 inch.
