I shoot the S&W sigma sw9ve 9mm.
I love it. I had to do a trigger mod (it was free). Now the trigger is 90% better than before. Holds 16+1. I can rock a milk jug at 25 yards (max distance that I practice).I have had no malfunctions. Breaks down just like a Glock. Under $300 price tag.
Sig p250. It is getting pretty awesome reviews and for what you can pay for a cheap gun of another caliber you can just buy the separate slide and barrel and make it a larger caliber. Same with the size of the gun, buy new lowers to make it subcompact compact or full size.
I own the 40 cal version and i have shot it a lot. Be careful to check and clean this model after shooting as it is an introductor pistol and cheap. I have had two for hd and trust them but the truth is they are kind of lower end. No shame in my game tho it fits my hand like a glove amd i havent had a single issue
I have the sd9 and have put a few hundred rounds through her in the past couple weeks without a single hiccup, for the price its a great gun. A little tlc makes its perfect for me
