Well, got the pistol back on this past Monday and took it to the range on Tuesday. Thirty rounds down range and same problem. Fortunately they didn't charge me for the repair. Same shop that I bought it at and I am a regular customer. They now have it back again. I have several CZ's and this is the first to ever give me a problem.
I would suggest the CGW spring.
Ditto, since they're about $7.00each, I'd buy 2-3, with any DA/SA pistol, the TRS is going to be the weak point, no matter if it's a HK,Beretta, or CZ, ALL have been known to break TRS's, it's just the nature of the beast. Plan on it happening, and have a few spares on hand, learn to replace them yourself, (this is where CGW's removable trigger pin comes in..if you have a P01, PCR,75 compact, or a full size 75 series pistol, not needed on the P07/09) and save some $$ Really, it's not that hard to do it yourself..CGW's TRS is, IMO, a higher quality spring, In the past, CZ has had bad batches of springs get out, unfortunate, but, it happens, the bright side is, CGW always has them in stock.
