Ordered & timely received trigger spring kit. Watched video & installed without issues. Much improved trigger. I'm a repeat customer and found M.Carbo's products top quality, good instructions, good communications. AAAA+ products / services
Just installed the sig 938/238 spring kit install ,polished hammer surface and feed ramp.....Omg what an upgrade.....game changer....I encourage all of you to do this!!
This was easy to install - thanks to their video. Don't have a trigger pull gauge - but it definitely lowered it. Good kit - and it didn't negatively affect reliability.
I watched the M Carbo video on how to lessen the 6.5 lb. trigger pull on my Sig. They made it look so easy so I purchased the kit. It was delivered right away and was easy to install as advertised. I now have a 3.5 trigger pull and have increased my accuracy a lot. M Carbo is an awesome company and I will be happy to do business with them again!
Quick shipping and easy installation. Install video made it simple. Second spring set I've purchased from MCarbo and will definitely precise again.
Great spring kit. Results were better than expected. Great quality kit. Very smooth and easy trigger pull. Easy spring installation. If in doubt, installation video was helpful with tear down and reassembly. Installed both kits in both my sigs when replacing plastic triggers to metal triggers. Brother installed a spring kit for his micro 9. He loves it. Definitely recommend M*CARBO spring kits. I love it. Very pleased with my purchase.
Very easy to install. Trigger pull at 3.5# now.
Price, service, delivery and instructional videos are excellent! The only problem is that the mainspring will not fit the Kimber Micro 9 series. Talking with Chris to develop a shorter captured mainspring to fit in the Micro 9 housing. Will not hesitate to order if it becomes available!! Death to Lawyer Triggers!
I installed the hammer spring and firing pin spring kit on my Sig p938. Polished the hammer and feed ramp as per the video. Trigger pull was 5 1/2 lbs. before the upgrade and is now 5 1/2 lbs. no change. I have used other Mcarbo parts with great results however I am disappointed with these. Richard
Just completed my installation on My Sig 938, polished feed ramp and trigger contact surfaces, installed spring kit, tested with a Wheeler Digital Trigger scale using 3 pull average readings. Results were, clean, smooth take up, crystal break and pull average greatly reduced. Before spring kit pull was at 5.7.3 lbs. After spring install and polishing pull was 2.7.1 lbs. Significant reduction and great feel improvement for about an 1hr of effort and little expense. Thanks M*Carbo I have another happy customer.
I have been carrying a 938 for about 4 years, ran across the video on the trigger spring kit, ordered it and did the polish work as described in the video. Amazing difference, butter smooth. Ordered a second kit for my wife's P238. Nuf' said.....
SWEEET!!! The installation video was excellent and when it came do the install it took all of about 25 minutes. The kit price is amazingly low compared to other gun type kits. The Sig P238 is my wife's carry gun and after I finished I handed her to gun and when she pulled the trigger her eyes lit up, her quote was "what did you do to it?" Just changed springs was my reply. At the range a close friend, who carries the same gun shot it and said give me the link. If you own a Sig P238/P938 tis is a great kit. Trigger pull on mine went from 6.5 Lbs. to 4.35.
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.
I’m 82 with slight arthritis in my fingers had no problem installing spring kit using You Tube Video. however, putting hammer pin back in had to have wife put pin in while I aligned hammer with hole and hold ejected back, she slid it right in. Extremely happy, it reduced trigger pull as advertised. I would highly recommend this kit. Great Company to work with.
I finished the installation on my P-938 and was extremely satisfied with the results. I did some minor polishing to the metal on metal areas of contact and checked the trigger pull before and after with a Lyman Trigger pull gauge, the result was a much smoother pull with a crystal break. 3 pull average before install was 6 lbs. 7.4 ounces, after install 3 pull average came in at 2 lbs. 9.4 ounces, a significant reduction. Thank you M*Carbo for another excellent product.
The kit arrived promptly and were in perfect shape. After viewing the installing video, I was able to install the trigger kit within a very reasonable time. Took the P938 to the range and had no problems with the P938 and was very well pleased with the performance. There was a considerable difference in the trigger pull which made shooting the P938 much more pleasurable experience. Put 50 rounds through the P938 with no problems noted. Thanks helping me solve a problem.
