HMMM. I think a hundred rounds at one sitting might blister ya, and it would for sure give your wrist a workout. Oh, that reminds me. Be sure not to limp wrist the little devil. Give it a good strong grip to resist and it will do just fine.
You can limp wrist a Glock and it will jam too. Watched several YouTubes on the P-3AT and it didn’t seem that jumpy, I’m a little disappointed it’s how you say. BTW, what is the trigger pull like? Is it a long pull? And does it have “stop rest” before it fires like a Glock?
