Hi 10mm lovers! I have a gen3 glock 20 with a lone wolf .40 conversion barrel. I shot it at the range the other day and as hard as I tried not to, I kept shooting high and left. Then when i changed the barrel back to the stock glock barrel and shot Hornady 180 I shot low left.  I had recently put a 21lb wolf guide spring in it. Could the .40sw be to slow for the 21lb spring and it's making the bullet stay in the barrel to long? I always shoot more left than right with my glocks and the ammo was 180grain mag tech.

Underwood has 10mm in stock!

I just bought 250 rounds for $125 at a gun show last weekend. I was dispointed after I bought them to learn that they were only 1040fps. I inspected every round and they seem to be fine.

I emailed Brooke from Underwood last week and she said that she will be stocking 180 TMJ withen the next couple weeks. On top of that she said that she was going to email me when they are in stock. Underwood ammo seems to have great customer service.

How tall is the glock 20 front sight? My blue label gen 3 glock 20 came with a scuffed up front sight. I dont wont to spend a lot of cash so i was planning on upgrading the front sight only then maybe changing out the rear sight if it was ever damaged. I want to keep some sort dot on the front sight so I can keep a good sight picture on black pigs.
