Having never shot the caliber, I wanted to rent a 10mm pistol, and the most convenient option was an EAA Witness, standard metal frame. I was a little apprehensive, having got the characteristic "trigger sting" from the Cz 75 9mm I tried last summer. It was a blast! (no pun intended) No problem with the trigger. Maybe the EAA's is wider.
Recoil was less than I'd expected. The shop said their 180 gr. ammo was "about 1200 fps." I'd forgotten what brand, but then I found a couple of casings in my range bag and it's PPU headstamped. Intertubez say that is only 990 FPS with 180 gr. bullets! Definitely 10 mm Lite. I knew I wasn't so tough! I was at the range last weekend and started trading guns with the guys in the next lane. One of them gave me ten rounds through his .40SW Glock, which didn't feel much different than I remember from the EAA.
The rental 10 mm functioned perfectly on this stuff, at least through one box. I'll assume that's with a stock recoil spring. (I'd call the range and ask but since they were about 40% off on the muzzle energy of the ammo, I wouldn't trust their answer anyway.) Plinking with something like this would be fine, but the fun of a 10 mm would be to go full-house as least some of the time. If I buy a 10 mm, I plan to load my own ammo.
How wide a range of velocity/energy variation can you get before it's necessary to go to a higher spring rate to avoid slamming the slide?
Are appropriate spring rates determined simply by muzzle energy, or is light and fast different than heavy and slow at the same foot-pounds?
