First of all you have an excellent weapon, reliable, functional, effective and for over 6K rounds in my case 100% failure free. I carry a 96FS in .40 S&W as it is the mandated caliber with the S.O. I have put over 12K through it with 100% reliability as well and have an INOX 96 that I shoot IDPA, mostly as we shoot regardless of weather.
I understand the raps on the design, check a post I did last week on the "Lethal Weapon takedown" like Jet Li did to Rigg's 92 FS. Like Shipwreck proved in a screen take, the weapon had the takedown latch already in the disassembly position and the recoil spring must have been out as the slide was not forward in any manner.
The stories from the Teams about slide breakage occurred in the early 92's but the enlarged hammer pin and the slide groove would preclude the slide coming off after breakage IF it occurred. You have to realize that the Seals shoot more in a year than most very active shooters shoot in a lifetime.
I have large hands and don't find the grip "fat" at all. It is one of the only handguns that fit my hand naturally. When I aim the weapon at an object and then acquire the sight picture, I always find I am dead on. If at the "funhouse range we have shots taken without acquiring the sights in simulated pressure situations are always right on target. I used the panel style Hogue grips until winter when I found the tackiness of the rubber grip seemed to adhere to my jacket lining. I will revert to the Hogue's for summer carry when I carry in the small of my back, palm out.
Make sure to lube the falling block as well as the slide rails. I use Machinegunners Lube available from Sprinco.com. It's a moly base lube that adheres well and stays where you put it. It is super slick and you use less due to performance of the lube. You draw your own conclusions as to what works for you. Everyone is an individual and has different needs and will like different handguns. Shoot well, often and safely.
