Does Lonewolf glock factory style porting require the stock slide to be refinished after being ported? Also which of these guns would benefit the most from the porting, a G21 or G23? I dont carry the 21 very often and it is mostly just a range gun, but the 23 will be a carry gun along with my 26 once T-shirt weather is over and I am wearing thicker clothing.
LWD uses an EDM to port slides & barrels. You can refinish the part if you like but the majority of shooters simply leave it as is.
The problem with porting the factory slides & barrels is the high content of carbon in the material. If the EDM electrode comes in contact with a flake of carbon it will "blow out" the burn and ruin the electrode & part. We have done a lot of factory slides & barrels and experience approximately 1% blow out rate. It is unfortunate and unavoidable, you need to consider this possibility before proceeding with a port job.
BTW: There is NO danger of a blow out with stainless slides or barrels.
