The title says it. I placed an order for 150 rounds of 180gr TMJ and 100 rounds of 165gr gold dot all from Underwood.

Of 80 rounds fired today, I had 3 FTE's where the slide bit the brass as shown. All 3 were with the TMJs.

I've been searching the forum and found that limp wristing is something I was guilty of today (this is my first time ever firing a pistol). The G20 recoil wasn't bad at all. I'm a fairly small guy, 5'10" and weigh 150 lbs. My groupings weren't impressive but I figure I have to learn the gun and its sights, and all of the moving parts have to learn to play well with each other.


The G20 is bone stock, these are the first 80 rounds aside from the test fire rounds.

My question is this, is my gun the issue, the ammo, or MY limp wrist for these FTEs? Every round fired, each felt the same in recoil, and the primers were struck perfectly. I know a heavier spring can help others, but I'd like to stay away from moving from stock as keeping it simple is typically the best.

Input please!

On another note, I was able to fire a 1911 Colt .45 that was a service pistol in Vietnam. It felt tame comparatively and trigger pull was very crisp

Since its your first time firing a pistol, and you went with a glock in 10mm, and firing true 10mm ammo, and your groups were unimpressive.. I would say limp wristing would be at the top of my diagnosis without firing the gun myself-

I thought you meant your first time firing a 10mm pistol, not just any pistol.

My suggestion is to get some low recoil 10mm stuff, like Federal AE 180 grain fmj or the CCI Blazer 200 grain. Figure out how your gun shoots with this, while at the same time working on your shooting fundamentals. Lock you wrist when you fire.

Then, once you and your gun are shooting okay, try the Underwood.

My guess on those 3 in the photo is you're riding the slide with your left hand. This prevents the slide from traveling full distance. Even friction from a thumb will slow the slide down.

Bob has probably diagnosed the problem. The slide might not be traveling all the way back. Limp wristing will do this, but interfering with the slide by the weak hand can too. The cases are not ejecting so are slamming home with an incompletely dislodged case.

With an improper grip, hot ammo can make the gun jump around a bit in the hands.

Underwood is a full load 10mm ammo, so I would look at other problems first...

When I got my G20 SF I first used several standard load rounds (Remington UMC and Federal equivalent) and they ran incident free.

When I started shooting UW full power loads with the stock 17lb recoil spring, the slide action sounded terrible, it was ejecting brass really hard and most of it looked chewed up.

I looked at UW's site and they recommended a harder (22lb) recoil spring for the G20 with their ammo and many others posted the same advice.

So I put a 22lb recoil spring in and it has run flawless ever since - 500 rounds so far (apart from 2 freak and faulty bullets that fragmented in flight).
