Sean,
Noticed your comments on the PM9, not certain but think the above is similar in size and thought ya might like to know:
I was teaching some females First-Step pistol classes weekend before last and the guy next to us at ASC had the above model. After watching him a bit, I struck up a conversation and as expected found out this was a full 9mm in quite a compact package.
I asked him if he'd had any cycling problems, given it's diminutive size and this is what he told me.
He bought it at the gunshow, it wouldn't cycle properly, so he sent it back to the factory. He got it back and it still failed to cycle properly, so he returned again. They "worked" on it and returned it to him, and this time he could get 3-4 rounds through it before it jammed. He returned the 4th time, (at this point I asked him directly, if he'd thought about "choosing" or making a different pistol selection, he said NO) and when returned the 4th time, it still would not make it through a whole mag without jamming, so He returned a 5th time. He was there shooting it and loving the hell outta it, and thought "I was crazy", for suggesting that a pistol which needed 5 trips BACK to the factory in-order to get through a magazine with no problems, wasn't something I'd be comfy with in my waistband.
Some folks "obviously" like the hell outta of 'em, just don't count me in that group!
Mike
