My personal opinion was that when Sig caved in to the polymer craze with the creation of the P250 the quality suffered somewhat. I have three P250's and I don't even like plastic guns. I try to keep in mind that when Sig Sauer builds a gun, they do it right, whether it's plastic or steel.
I never cared for striker fired guns, which is what the P250 is. I bought my first one, I guess you can say, by mistake. Someone was offering a 9mm Sig Sauer pistol at a fantastic price so I bought it. I did not know at the time that the 250 was made of plastic, I didn't know that SIg even made plastic guns.
I have had striker fired pistols a couple of times before and hated them. When I first fired the P250, the thing shot great even for a DAO striker fired pistol, but still it was plastic. I tried to sell the thing and it seemed like no one wanted it because it was a P250, so I just kept the thing. I eventually liked it so much that I bought a .40 S&W Xchange kit for it (.40 Cal barrel and slide). Then I bought one in .45 ACP and I love it, too. I let my son use the .45 on his job (after I took my 1911 away from him) and he liked it so much that I just let him keep it.
After owning three of them, my opinion has changed and I no longer think there is any lower or less quality with the P250,
