The Ruger® Mark™ Series is a favorite for rimfire pistols for competitive shooting sports. The TANDEMKROSS Maximus Plus1 Follower for the Ruger® Mark™ Series is a drop-in upgrade that makes your gun competition ready, whether you’re shooting a Ruger® Mark IV™, Mark III™, Mark II™ or 22/45™. The Maximus Plus1 Follower allows the user to load 11 rounds into a standard 10-round magazine; ideal for rimfire competitions that allow the shooter to start with 11 rounds. The follower is made of durable Zytel® and is bright red, improving safety by clearly showing the shooter when the magazine is empty.
This is a simple, drop-in upgrade and does not require any special tools to install. The Maximus Plus1 Follower is sold in two-packs and works with both the factory magazine base pad and TANDEMKROSS MarkPRO Magazine Bumper for Ruger® Mark IV™ and MarkPRO Magazine Bumper for Ruger® Mark IV™ 22/45™. The followers will also work with our extended magazine bumpers for Ruger® Mark III™ and Mark III™ 22/45™
Don’t waste time in competition with a 10-round magazine. Load more ammo with the TANDEMKROSS Maximus Plus1 Follower for Ruger® Mark™ Series!
NOTE: The Maximus Plus1 Follower is compatible with any Ruger® Mark™ factory magazine base pad and all TANDEMKROSS extended magazine base pads. However, using the Plus1 Follower with a TANDEMKROSS Plus1 magazine base pad does not enable the user to load 12 rounds in a standard 10-round magazine, only 11 rounds.

about the +1 followers
Item works as advertised. I installed using a stock Ruger spring. I have had no problems of any kind. Locks back after last round. Colored follower helpful determining empty/safe at a quick glance.

Easy install, held 11 as advertised but I did encounter one problem. Sometimes bolt didn't lock open after last round was fired.

It was time to disassemble and clean all my mags, so why not upgrade the followers also. The followers definitely slide smoother inside the mags, I’m indifferent about the the extra round, but is ok.

Failure to lock open
Works as advertised. However have been noticing failure to lock back on the last shot more frequently

Ms.
Plus one followers function perfectly and eliminate the need to carry a "Barney" magazine in competition!

Mr
These are great. These followers are a little smaller to accommodate one more 22 round in the magazine. Can't go wrong with another round! They area also snazzy red. Note: One of mine snapped at the range. I had the spring totally depressed and then released it with no ammo in the magazine, and I think the spring was too much for the little plastic and snapped it. I took a pic and sent it to TK and they emailed me a replacement pair ASAP. They said these breaks are super rare. Great service, thanks TK! I'll be back
