Question: Will the grips fit on S&W 686 square butt?
Document: I purchased these grips for my s&w; model 642-2 from Amazon mistakenly for a square frame. I bought it before the gun arrived and found that gun was actually a round frame. It contacted Amazon to return them for an exchange and they told me that the 30 days had passed.I managed to get Pacymayr to exchange them for round butt and the fit under the trigger guard was not good. I have emailed Pachmayr to try to exchange them.
The Pachmayr grips for the 1960 Smith & Wesson model 36 Chiefs 38 special have drastically changed the fit and feel of this revolver in a good way. This is the model 36 with a square butt and has a 3 inch barrel. I shot this revolver at 15 yards with a score of 140/150, 13 of 15 in the black (15 total rounds fired) with good comfort and accuracy which was difficult with the original grips.
Fit my Smith & Wesson Model 36 Chief Square Butt like a glove. The feel and handling of the weapon has improved 100% with this grip. Less than 60 seconds to install.
The grips fit great on my S&W j frame. They made the revolver more comfortable to shoot and felt great.I would recommend these to anyone who likes to use their gun for range shooting. They are too bulky for concealed carry though.
These grips arrived quick and fit great. Made my S&W model 37 airweight look and feel great, installed in 2 minutes. Great for a mans hand and slim enough to concealed carry. Definitely a great replacement for the stock small wood grips.
The stock grips on my S&W; Combat Masterpiece were servicable, but left considerable room for improvement. The Pachmayr Grips fit my hand much better than the stock grips and afford much more comfort in my weekly trips to the range. The recoil management with the Pachmayr Grips is vastly superior to the stock grips with full house magnum rounds in every respect.I couldn't be happier! It's like I have a new and improved version of a revolver that was already my favorite!
The Pachmayr grip for my S & W .38 cal was a great addition to the gun. Makes handling of the gun much easier. Great fit with little recoil.
Would rather had grips with built in laser. But no one makes them for the square butt. That's all for now.
This seems to be an odd item,and hard to find,Hard rubber grips for a J frame square butt.Majority of the J frames come with the round butt.These grips are a big improvement over the oversized and ill fitting wood grips.
I had been looking for a set of grips that finger grooves for my square butt frame revolver. I had almost given up and was going to have a gunsmith round the frame. I'm glad I looked on Amazon before I altered the gun. It was just what I was looking for.
Answer: yes
