mp40c threaded conversion? ??

[elliotyee215]

Hi I have an m&p40 pro and I was looking to convert it to a 9mm . I was Looking at the sl threaded 5" barrel. Would it work with the 4.25 pro core? ?

Bump? Can anyone help

Welcome to the forum. Sorry, my only suggestion would be to contact SL since you're inquiring about one of their barrels. They should be able to give you that info. Good luck.

Storm lake does NOT make a 9mm conversion barrel with threads for the 40c (compact).

I have a 40 pro core

Does anyone know if I can even put a 5" barrel in a 4.25" frame?

I never tried, so i just did. Yes it will physically fit and function. I haven't shot it and looking at the larger section of the pistol at the muzzle, I wonder if accuracy would suffer (I think it would, but have no experience trying it and don't plan to )

I took my mp pro to the range today with the new sl 5 inch 40 to 9mm conversion barrel. Fits great unfortunately Had multiple stove pipes and failure to eject. Recommend this barrel for range use only.
