I just purchased a used Smith and Wesson 3913, in decent condition. It is not the LS, but it is DA/SA. Overall, this is a great little gun, and I think it is worthy of replacing my M&P PC Shield as my carry gun but I want to get the bugs worked out first. I think it needs a little, hopefully minor work and I am hoping someone here might have some quick answers for me.
(1) Failure to return to battery
It looked like someone did not use it for a while and it needed a clean and lube. I shot it prior to the clean and lube, and I had intermittent failure to return to battery issues where I just had to gently push the slide about 1/8 inch to continue firing. I did a clean and lube with Lucas oil. My BF also thinks the feed ramp may need some smoothing.
I took it back to the range after the cleaning, and no more issues with failure to return to battery. I am not sure if the clean/lube was the only problem. I am going to get a new recoil spring. I am hoping that I really do not need to do much with the feed ramp.
(2) Take up in Single Action mode
The Take up in SA mode is gritty, not smooth, almost feels like it is "hitching". If I shoot and do not let the SA trigger back out, no issues. If I shoot DA, no issues. It is only if I let the trigger take up all the way out before firing in SA mode, that I get that gritty, not smooth feeling. Any ideas of what this might be? Also, the safety feels a little gritty. I am wondering if I just take the Lucas Extreme Duty Contact Cleaner to the trigger assembly and safety, if that will do the trick. I am not sure if I should do this without removing the firing pin, and that looks like quite the project on this gun.
Any ideas, feedback, are welcomed.
