It's compensated in the rear, which their addition of the back straps. Which are apparently removable, if it's not ur thing.
However, if that's the case just get the gen 3. Essentially the same gun, caliber, and quality, just with the standard Glock grip, no back straps.
The Glock reps say the added back straps on the gen 4 is to raise ur hand position higher on the grip, and in doing so you will increase your accuracy. I always felt as if the beaver tail in my 1911 did wonders in keeping my grip tight & right, and kept my groupings tight n never had n e issues hitting my targets.
I was looking into a gen 3 Glock 31 actually an stumbles upon ur post, and after some research I myself will probably just shell out the extra 50$ for the gen 4 as the added features truly seem incredibly useful. Rather than just cosmetic, which lets face it, generally all gen glocks look EXACTLY the same. But u gotta love the simplicity and reliability. Also you gotta god [censored] love that "nerve damage" .357 sig.
Hope this helps
Hey, welcome to BITOG. Anything related to .357 SIG gets my attention. One of my favorite handgun calibers!
Hard to beat 1500+ FPS/600+ lb/ft. of energy out of my 4" barrel Glock 32 with Gold Dot bonded, jacketed hollowpoints loaded by Underwood Ammunition.
AND the 15-round as well as the 22-round factory Glock magazines fit, in addition to the stock, 13-round magazines.
If anybody knows of a smaller, lighter, higher-powered, higher-capacity semi-automatic pistol, let me know, will ya?
