I'm sure it's been answered before but my google skills seem to be failing me, but I'm swapping out the stock 17lb recoil spring on my G29 with a 21lb Wolff guide rod/recoil spring assembly.

This should successfuly handle Buffalo Bore's 220 grain HCFN, right?

Also, I can only seem to find the ballistics for the 220 grain HC out of a Glock 20 and other firearms with a 5" barrel. I know it's going to be slower and have some less ft/lbs but I'd like to know by how much.

Any help would be appreciated
