Locking block falling out is normal, a few do, most don't, but no problem. Beretta 92s feed ammo fairly straight... length shouldn't be a problem. Might try factory ammo until gun is "broken in", or reduced power recoil spring with your ammo.

Keep the locking block properly lubricated and change the recoil spring at proper intervals and there won't be a problem. I've shot hundreds of thousands of rounds through Berettas and have never (knocks on wood) broken a locking block. I've worn out an aluminum frame (chunks cracked off).

Dovetail sight plates here and more: https://americanprecisionfirearms.com/product-category/parts/handguns/beretta/beretta-92x-performance/ The front sight dovetail is Brigadier cut. https://dawsonprecision.com/sights/beretta-sights/

If needed, I use the Wilson extra power extractor spring and I've even dropped one of these little parts in: https://www.brownells.com/gun-parts/rifle-parts/rifle-bolt-parts/ar-15m16-extractor-buffer/ Usually, as the gun breaks in, the extraction problems work out.

I wanted the "match" gun and "practice-backup" gun to be identical. I still have it... https://www.dlahdesigns.com/shop

I never used it and went with the LTT cut (so the guns would be identical).

On the left is the LTT RDO cut, the right is as low as you can go with a plate (skelatonized). Both 92XP Defensives.

AND they have a pretty nice arch.

Wide, great traction: https://www.skechers.com/arch-fit-glide-step-trail/237535WW_CCOR.html

I voted for 15 rounds, but 140mm magazines are the real answer.

Maybe?

Sand/file the inside of your LOK grip where it rubs on the trigger bar. Smooth the edges off of the groove in the grip.

I have a few. Slick, really have to tighten mag pouch adjustment down. 23+1 for sure. (Someone may get 24, but I don't.)

How did you find a slide racker? I've wondered if a 9x21 barrel would be good for a Beretta Open gun?
