I am going to concern S & W M & P shield 9mm but actually I don’t like DOA gun because the trigger is too heavy , is it said that shield 9mm’s trigger is 12-15 lbs ? If someone can recommend a 9mm pistol with Single/double action, the price is not greater than $350 will be appreciated. Please tell me your opinion about shield 9mm.or it's trigger safety.
I always think it's better starting with a purpose/problem and then looking for a solution. I don't really believe in "general purpose" guns anymore, so it would really be a bit of help to know what you want the firearm for in the first place.
That said, I just added a S&W M&P Shield 9mm to my collection about a month ago. I just finished putting about 250 rounds through it yesterday. With the rebate program (I think it just ended, but it's worth checking) it cost me under 300$, I believe. It's an excellent bigger-than-pocket-gun,-smaller-than-9mm-double-stack gun. I basically purchased it for concealed carry when I want something bigger than my LCP but thinner than my Ruger SR9C. And as that, it's great. Trigger is average, in the positive sense. No better or worse than you would come to expect in a cheap, small gun.
I think other manufacturers have done a better execution of the trigger safety, and until you wear off the sharp edge on it from use it's a bit annoying to get used to depending on how you press the trigger. But it isn't anything you'd notice during actual trigger time at the range. Unlike the LCP, it's a pleasant pistol to shoot. It's a bit jumpy but not unmanageable. Sight radius does affect accuracy, but nonetheless it's enjoyable. In other words, perfectly useable and good for a cheap, small gun.
Size wise it's great. It's small enough to pocket carry in larger cargo pants, and large enough to comfortably and securely carry it IWB in a Remora holster. It's very thin, which is why I bought it and I wasn't let down. Weight wise is what you'd expect, not really very decisive for me. I also liked that the slide is stainless which is great for reduced maintenance in rust-prone Florida.
Apparently Smith Shield triggers vary a lot
I was pending measuring it anyway after breaking in, so I might as well do it now. The trigger pull on my shield is: 7.5, 6.5, 7, 7.1, 6.6 (lb) for an average of 6.94 lb using a Wheeler Trigger Pull Scale. It's a bit hard to measure while tripping the trigger safety so I'd imagine that's the upper limit of what an actual finger would need to exert.
Hope the input was helpful. And if it wasn't clear by now, I'm perfectly happy with Shield 9mm. Only wish I had bought it sooner. But I would probably be saying the same thing had I bought an LC9 so take it however you will. Most any popular firearm within your budget from a reputable manufacturer will leave you satisfied these days if you don't have stringent expectations.
