Very nice
The original old one was pretty worn out and dirty. It was time to change for the better.
Great product.
Not the first item I have bought. Very satisfied with the quality of the product. I will continue to purchase items from MCarbo.
Works as advertised
Made a big difference in a stock Glock 19 just by dropping it in. The spring is lighter weight, but hasn't effected anything in a negative manner. Will be getting these for the rest of our Gen 3 Glocks.
New Firing Pin Safety
Installation was a snap.I don't think it reduced trigger pull as I had previously polished OEM firing pin safety..I installed in all three of my Glocks and am pleased.
For use in polymer 80%
No doubt you've run into slide drag issues on your polymer 80. This plunger corrects 2 of the problems.
You can find a YouTube video on polymer slide drag, that will solve the other 4 issue.
The only other part you'll need to buy is the 20# recoil spring
Do you offer the polished firing pin safety for Gen5 Glocks?

Unfortunately it is only for GEN 1-4 at the moment. We may offer a GEN 5 version in the future if their is enough demand for it.
Is this user installable? Or does it require a gunsmith/armorer?
If you are capable of disassembling your slide completely you can do it.
