Shield 40 renewed
review-star review-star review-star review-star review-star
I found the M*Carbo kit to be extremely easy to install with the video. My pistol has new life and I can feel the difference in the trigger pull/response at reset compared to the original components. I bought my Shield 40 slide assembly via Ebay and changed my 9mm over to the 40 cal. I am ecstatic about the performance difference. My 40 is very controllable and a pleasure to shoot. Thanks M*Carbo.
3.3lb consistent trigger!

I've been a gunsmith for more than a decade, I've seen my fair share of promises from items that doesn't come close to advertised. This is Not that, I installed this kit for a customer and with polishing, spring swap, and alil trick I have to adjust alil pre travel. I'm getting a consistent, drop safe, pull of 3.3lbs.

I installed the spring kits in my shield 2.0 .45 and my dads shield .40, absolutely a great value for these kits and made both of these completely different guns. The factory triggers were about 7lbs and rough, after the install triggers are around 4.5 and much smoother. The price point is great and the videos were very useful.

BLUF: Once I got it in, the kit worked great...just as advertised. Apparently S&W used red Loctite to also glue my rear sight to the frame so I went through two brass punches before being forced to use my Wheeler steel punches. The wooden dowel never had a chance. No material damage and the slight cosmetic nerfs were quickly repaired with frame paint. The installation video was perfect, and although I dont share the same love of polishing, it seems like it really paid off. Weapon shoots great and has improved my Dicken Drill times by about a second. Great, well thought out product.

Spring kit made a HUGE difference in my S&W Shield 40 build. Trigger is now crisp, clean with a definite reset point. Install was fairly easy using Youtube videos. Highly recommend MCarbo spring kits.
review-star review-star review-star review-star review-star
Well all I can say, you better hope you get all the right parts. I ordered a spring kit for a Shield. Everything was good. Until it came to the striker spring, it was too small. Emailed MCARBO about the problem, thinking it was going to be handled. But my request was pending until I left feedback. That's been a week and half ago. Still haven't heard anything. So I'm leaving this feedback, don't know if it's going to do any good. I'm doing what they asked. All other parts were top notch. There's no after sale support.
Works great
review-star review-star review-star review-star review-star
I have a M&P 2.0 in .45 MA compilant
( 10lbs+ trigger pull) With the spring kit it went down to 5.5 lbs trigger pull which is way better. For the price its amazone results

Thanks
