Has anyone heard of after-market porting for the Glock 29? Have 2 10mms now and love em.?

I'd like to compare recoil. My Delta Elite is fantastic but after replacing 3 fillings, I decided to have it compensated. We adapted the LAR Grizzly win-mag compensator to fit the Delta. Still kicks but not like before. The Grizzly has 4 different barrels and mags, one of which is 10mm. There is hardly any kick at all with this heavy gun.
