Hard cast bullets with 10 mm Glock

[KSB209]

I have been told by a couple gun smiths that if I am going to shoot hardcast bullets through my Glock 20 i need to change the barrel. I'm not "in the know" on handgun barrels and looking for suggestions. The only one I really know of is Lone Wolf. What are some other options? Also wondering how bad is it if I do shoot hardcast through a factory Glock barrel. Is it going to cause major damage or is it just going to wear down the barrel fast and/or lose some accuracy compared to standard hollow points

Very interesting! I'd like the information regarding my 2 Springfield Armory 10 mm's. Thanks for asking!

I've shot hardcast in both my stock 29 and my 29 with an extended barrel…storm lake. The stock barrel wouldn't stabilize them and they went in sideways! No issues in the storm lake, which is about 1" longer.
