I never regretted purchasing my BT22. I deeply regret selling it, and plan to get another one. Its a very good gun, but its picky with ammo. As for the trade, I can't say for sure. The dealer has to come out ahead so he can re-sell it, but I honestly don't know what a CM9 is worth. A BT22 is almost $300 new, though its possible to find some for a little less.
I love my SR22. Absolutely perfect from the beginning. I like the adjustable rear sight (wind age and elevation) and the ergos. DA trigger is stiff and gritty but, SA is very nice. I don't think you'd be disappointed as long as you didn't have to overpay.
I disagree with hammer bite for the ppk/s 22. ive taken mine out 4 times now and neither myself or others have ever experienced it one time
Oh, it won't getcha every time but the PPK has always been noted for an occasional bit. The PPK/S is just the PPK upper on a PP frame to get past the 1968 gun restrictions. My PPK could go for years behaving itself but it was always waiting for a chance. And actually the shape of your hand can have as much to do with it as anything else. If your hand is not very fleshy between your thumb and 1st finger you may be good to go.
