P238/938 spring kit

I purchased the first spring kits mcarbo put out for this gun. I bought two one for p238 and one for my p938.
Videos were super helpful for install and polishing surfaces. Thank you for that.
I do not feel a noticeable difference in either fire arm from the spring kit. However, I do not have a Guage to verify. I am not seeking to return either kit. Since both are GEN 1 I am unable to utilize the new addition of the improved sear spring. The customer service was excellent as we did talk through this issue.

Night & Day difference

I recently bought 2 of these kits. 1 for my gen 1 p238 & 1 for my gen 2 p938. I cerakoted my P238 first & as soon as I was done re-assembly went very easily with the new Mcarbo kit. This is of course after I bought a new gen 2 main spring housing. Re-assembly of the complete weapon was about 25 to 30 min. So basically if you are just doing the kit, after watching Chris's video it shouldn't be more than a 20ish minute job. My trigger pull on my P238 went from 7lbs2oz down to 3lbs 4oz. As the title say, the difference is like night & day. I highly recommend this kit to any p238 & p938 owners.


Great deal all around

Super fast shipping, Great video, Good follow up by email. I was able to install with no problems. I bought the p938 with the FT Bullseye Site (as expected...sucked like most reviews) for snag less draws, I always use a laser on my carry guns anyways. What I didn't expect was the trigger pull. I would constantly tweak the gun and hit far right. The trigger pull weight was a lot of that but also felt like the trigger it self pivoted down more than pulled. I also installed a flat Galloway Precision trigger with this kit. I didn't have a trigger pull gauge but it is not the same gun now. It is more than half of what it was and my groups tighten up tremendously. I would highly recommend this kit for you p938 and the company for there commitment to customer satisfaction.

Sig Sauer P238 Trigger Kit

I have field stripped guns and rifles before but have never taken them apart further. This was my first attempt. So I watched the video and followed it rewinding to repeat as necessary. That can get messy when you are dealing with the polishing part. The video was fantastic. Following it made everything so easy.
