I bet. I have read multiple folks saying the same. I once had the Sigma S&W. At the time, it was not my thing and I traded it for a revolver before shooting it. When I bought it, I remember the guy who sold it to me telling me he had put an Apex trigger in it. I had read reviews on the Sigmas prior to buying it and they were kind of like the M&P, reliable, but the trigger. I remember putting in snap caps and being impressed by the trigger. Thats my small amount of experience with any Apex stuff. Were I going to use these guns for more than nightstand duty and an occasional range fun run, then I would certainly invest in the Apex stuff. Everyone seems to love the improvements they bring.
