I'm looking to get a polymer framed 9mm. The catch is I'm a lefty. I've been told Golcks cant be modified. Sigpro has ambi mag release, havn't heard anything about 9mm version. CZ100..not sure of anything ambi or how it shoots. Walther P99 I've heard some horrer stories about jamming and breakage. Steyr, deosnt look like anything ambi. This will be my only 9mm for a while, so I want something that will last, and shoots accurately. If modification not too expensive, I may consider doing it. Any suggestions?? Thanks.
