Do you own a 617 and a 929?

I believe The 617 is a K-frame and the 929 is built on a N-frame. Different grips. The capacity difference will make the DA trigger different in both guns too, as for SA trigger, should be similar.

A 986 is an L-frame also chambered for 9x19 so the grip frame would be the same as the K frame 617.

But, there would still be a weight difference and DA trigger difference between the two.

I consider my 4 inch 617 as kind of an understudy to my 4 inch 686. There is only maybe an ounce difference in weight and length and balance are very similar. Now if I could just get my 686 to hold 10 rounds of 357......

I have a pair of revos, a 5" 627PC (N frame) and a cut down 5" 617 (K frame) that are matched as closely as I can get them. Weight and balance are the same; trigger pulls are both the same and beautiful. The 617 makes a great surrogate gun; shoot the .22 for much of a practice session, then finish up with the .357. Good practice and keeps costs down.

I own a Model 17 (no dash) made in 1959. One other K frame a 10-5.
