S&W Model 317, and Model 36

Pros:
Cons:
Bought 2 J frame spring kits for the aforementioned revolvers. The Model 317 Kit gun had an original trigger pull average of 10.8 lbs. After the 10 minute install of the spring kit, I was pleased to see a 5.2 lb. trigger pull. Since the install I have lost this gun......it is now my wifes favorite. The Model 36 not quite as impressive as the 317, went from an 8.4 lb trigger pull, to a 4.9 average. Again my wife is happy, because this is her second favorite gun now. I am well pleased with the outcome of both kits. Testing will be this weekend! Keep the kits coming!

The Customer Service is 5-Star. A great group of Patriots.
I'm reasonably technical so the installation went well. The trigger pull went down from 13lbs to about 8lbs. I would have prefered a little less, but I'm considering a break in period.
These folks are great to do business with

Cons:
This company has outstanding customer service. There're are great videos and written instructions to help with instillation. I was a little disappointed with the springs. The stock trigger pull was 12+ Lbs. after the new springs it was only reduced by about 2 Lbs. I sent an email to their customer service asking about this. The next morning I had an answer to my concerns. Answer...the trigger pull will lighten up more with use, kind of thought that but what great customer service. I like this company!

Major Disappointment

Rating:
Pros:
Cons:
The gun had a 10.5lb trigger pull and after watching their product video and reading the description I was excited to install this spring set and would have been happy with anything even close to the advertised 6lb DA pull weight. After installing the spring kit, to my surprise, the DA pull weight actually increased to 12.5lb. Extremely disappointed. I ordered another spring set from Wilson combat.
