I have had two 940's and recently a Ruger LCR 9mm. I like the niche they fit, as I went exclusively to 9mm self defense weapons. The guns recoil is pretty harsh. The LCR did crimp jump on me once, with cheap ammo. For me, installing a larger grip on the gun took away from the purpose of having the thing, concealment.

There are a lot of folks out there who like the 9mm's revolvers, and the supply is drying up. Good luck
