This 9mm SD was my first semi auto and had a time with it and after get it shoot the way I want.All I shoot out of it mainly is cast that I made up my self and works for me. I still have it ,I got a M&P in 9mm and works for me.I keep what ever I get and make it all work for me.Beside I reload and cast of all of what I have. I let the gun tell me how to use it and go from there.I have some other 9mm and they have there own use.One thing about 9mm alot of times for most of the 38/357mag cast bullets I cast can be use as is or size down for the 9mm. I was stated that this gun we are talking about can take abused . Can someone explain that for all it can take? I did see a video of the M&P 9mm can take .
