Great improvement
I just got a new Mark IV to go along with my Mark III. These bumpers let me make all my existing magazines work with both pistols. Plus they make for a much more positive magazine insertion. A great addition to my Ruger pistols.

I purchased 4 of these and it's amazing how fast you can strip a mag out and reload they are not to bulky.but just the write size.

Absolutely PERFECT!! I bought 10 of these for my Ruger Mark IV LITE. The bumper pads are very simple to install. They perform exactly as they were advertised. I HIGHLY recommend them!

"MarkPRO" Magazine Bumpers for Ruger® MKIV™ 22/45™ (2-PACK)
Pads are nice but have a design flaw that causes failures to feed problems. The location/ANGLE of the hole for the guide rod in the base pad is incorrect. This causes the recoil spring to rub on the mag body. It is easy to check. Take a mag and remove the spring & follower, install base pad, take a rod the same size as the hole in the base pad and insert into the bottom of the base pad to see if it lines up with the spring channel of the mag or is it angled towards the back of the mag. The binding of the recoil spring causes failures to feed problems.

Mag bump
These bump pads make seating magazines a breeze. They also extend the grip a bit, helping to purchase the gun better.
