Sorry to hear you got cz, s made on Friday the 13th, though I notice that despite having trouble with one you went out and bought another
I can,t speak for the omega as that's a bit of an unusual design being able to be a safety or decocker rather than one or the other which is a sturdier design. (I think your better of with either the de cocker or safety model.)
I disagree with your statement that "that if the goal is to survive long term use, a pistol being used in competition means nothing" I would say this means a lot..the average sig P series/beretta owner probably shoots 1000-2000 rounds a year if that. A serious competitor shoots 5-10,000 plus rounds per year and shoots week in and week out. A competor isn,t going going to stay with an unreliable platform that craps out on match day. Sure you may have to replace a slide stop or trigger return spring after 20,000 rounds, that's maintanence, do you have to do that with a sig or beretta? It takes so long for the round count to get up there when something goes the gun is like 20 years old so no on knows if the,re really that sturdy. The sig X5 is a competition gun that see,s high round counts and it certainly has mantainence needs as the round count goes up.
What is PF??? I don,t get out much
