I watched your video and want to order the kit, but you’re not offering the trigger spring anymore. I believe my P938 is the original model since I don’t see a Gen 1 or 2 on it. The trigger pull on it is around 8-10 pound pull and for sure needs a lighter trigger.
Installed following step by step video. Changed out P238 and P938 during one session. Have the correct tools and some patience toward the end and you end up in the success column. Results using a mechanical Wheeler trigger pull guage over 5 resets. P-238 is now 5.0 #; P-938 is now 4.25 # Did not have the guage prior to upgrade but results are in line with results advertised. Results at the range were impressive resets and rapid fire.
I liked my SIG 938 with a bit of trigger work and then installed the M-CARBO spring kit. Much easier then cutting or experimenting with factory springs. I used my Virus money to buy a second SIG 938 for family/back up and bought the spring kit again. Its a good system.
Watching the video with it’s great pictures and detailed descriptions it makes it easy. Would recommend their products to everyone. Their prices are wonderful and shipping is great. The people on the phone are great and so is their tech help. Why would you go anywhere else? Tom
This kit reduced my trigger pull fro 5 to 3 pounds. I followed the video which included polishing the hammer. I would recommend it.
Hey. Awesome outcome, I do have one suggestion for guys like me with old eyes and big fingers. After blasting my safety spring and decent around the house I finally bent the spring beyond use. Made an order to Sig and ordered the spring & detent (x2) got ‘em in two days. In the meantime was thinking about what to use to get that little devil in there. I finally used a nail set with a convex dimple head and it was unbelievably easy. Hope this helps. Reg
I thought the trigger in my Sig P983 could be better. I searched trigger kits for the Sig P938 an came across M CARBO found the kit for $15 and watched the install video, it was great and I saw it was no big deal to install. So I bought the spring kit. I don't have a trigger pull guage so I don't the numbers so I won't know how much improvement there will be. I installed the kit yesterday and polished the trigger as per the video , easy job. The trigger feels better. Shot it gun this morning , put 100 rounds of 124 grain through it. I'm very happy with the results , much nicer gun to shoot. Well worth the $20 with shipping. It took 2 weeks to get the kit from when I ordered it , I called them after 8 days. The girl was very nice , she checked on it and told me due to Covid 19 things were a little messed up. I kind of thought that before called anyways. That's the way things are at this time No Big Deal that's life. I am looking forward to dealing with M CARBO in the future.
Used this kit for a lady with small weak hands and results were perfect for her needs. Also very simple install.
I installed the spring kit in 2 P238s. I followed the video produced by M CARBO. Great instruction every step of the way. Lighter trigger and works excellent. I recommend this and will purchase from M CARBO again.
Wish they made sear for the smaller hole, may that would help,
I have MS so was looking for something to reduce the trigger pull. I have two p238s so I had a good "before and after" test because I just installed the MCARBO kit on one and not the other. Very disappointed after installing this two spring kit. There is no desirable reduction in the trigger weight pull. I have a couple friends at the range to do the same test and they agreed, there was no difference in the trigger pull on the two guns. And yes, I polished the hammer. Very disappointed.
I tested the stock set up after 500 rounds, then cleaned and oiled. Surprisingly the average trigger pull was exactly the same for the dirty and clean gun at 6 lbs 5 oz. I did the polishing and retested 5 lbs 7 oz. then I installed the new springs and the average pull dropped to 5 lbs 5 oz. Great how to video. I Shot the gun after the polish and spring install, it operated flawlessly, trigger felt much smoother. Trigger pulls were done with 8 pulls for each test and then averaged.
Great products cheap easy to install . Lowers trigger pull in half. Easy to follow video for install. Worth every dime
When I installed the springs on my sig p238 I automatically saw a difference on the trigger pull thanks for the awesome service and products.
Let my start by saying that my P238 was purchased in 2010 and has very few rounds through it. Mainly because of the very gritty trigger that pulled between 7 and 8 pounds. After the new springs were installed and a good polishing, as recommended in the M*carbo video, the trigger pul is running between five and a quarter and six pounds. Not a much weight reduction as I was hoping for, but the pull is much smother than before. I attribute the new smoothness to the time polishing with the M*carbo Polishing Kit. All in all the kit was simple for even an old man to install and doing what it is supposed to do.
