    Trigger spring kit

    Received my trigger spring kit in three days. Took it to my gunsmith said he could not install it for days because he is swamped with work right now because of people buying guns because of the coronavirus. So I figured I will try and do it myself using the video that Mcarb looks o supplied. Was such an awesome help I was able to do it myself with the video. Thank you M carbo


    First time got it done

    This was my first time modifying a weapon and it went amazingly smooth with the video and included part.

    Much smoother and lighter trigger pul . Once this 'Rona lockdown is over I'm going to the range!!

    Improved Trigger Pull

    Item was exactly as described. Installation was a snap with the video. Shipping was fast and hassle free. I would definitely recommend this kit if you have one of these pistols. I would also buy from MCARBO in the future.

    Thanks for the quality product!

    Arrived quickly and by following the video fit right in! Wow, what an improvement! Saved me from selling at a loss! Now it's a keeper!
    Thanks again!
