Here's what a Glock 39 offers me.
Lower cost than a Glock .45 ACP or 10mm in the large sized Glocks.
A person can often find the 39 and other GAP pistols at much lower pricing than
other Glocks, even including some 9mm, 40 and .357 SIG Glocks as well.
The Mid-Sized Glock 19, 23. 32, or more specifically, Glock 26.27 , and 33 frame
with a Glock 45 ACP slide, but not that of the G36 or G30S pistols.
Most cite lower recoil with their Glock 39 s or other .45 GAPs, due to the
fact that there is that heavy slide and also the fact that while the 185, 200
and 230 grain .45 GAP loads are as powerful as .45 ACP loads.
The .45 GAP
uses a small pistol primer.
I also don't like how my middle finger gets rapped by the larger framed .45 ACP
like my G36. The underside of the trigger guard feels too wide.
The G36 also has a bit too much recoil for me, even with 230 grain
FMJ.The Glock 39 is heavier and has a wider, heavier slide, or I'm told.
While the .45 GAP, and Glock 39...
offers me these advantages.
The fact that I'll probably have to ask the local shops to order me ammo..
or by it online at much cheaper pricing.
I have seen more local .45 GAP ammo in the past 3 years than I've seen
.357 SIG or 10m,, of which I shot .357 SIG for 2 years and TEN for 8 years.
I've owned BABY GLOCKs in G26,
but never one in .45 GAP
My Glock 36 will be replaced by a G39, and that will hopefully allow me a G26 sized Glock..
only with a bigger slide, to have .45 caliber stopping power.
Not that I don't feel under armed with my Glock 43
