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.

Great Upgrade for the MKIV

A huge improvement... TUNE AND POLISH YOUR MAGS FOLKS!
I ordered a brand new #Tandemized Mark IV Lite race gun and bought 4 new magazines to go with the 2 that come with the Mark IV. I ordered the green springs, the +1 followers and the brass buttons for the magazines that arrived before the Mark IV. I took the time to tune and polish the magazines (Tandemkross has a great Youtube video that goes over this process) and the installed these upgrades... I promise, if you do it right it makes a TON of difference. I have had a number of .22 LR pistols over the years and all of the magazines felt cheap and very gritty. These are smooth as silk as long as you put a little bit of time tuning them. Easy to install all of the part upgrades and they run flawlessly! Don't just upgrade your guns and ignore the magazines, upgrade the mags too!

Plus 1 Follower
I installed the Plus 1 follower on 2 of my Ruger Mark lll / lV magazines. They work as advertised and give you one extra round. I have had no jams or malfunctions shooting them in my Volquartsen Black Mamba pistol.

Awesome Followers
These work great. I thought they didnt work properly at first since I tried swapping the loading assist button to the other side to make loading easier and it wouldn't lock back. But after swapping it stock position it locked back.

renew follower
Very pleased with this product and the follow up service. Was experiencing FTF problems with 6 Ruger magazines. Ordered 6 of these units along with the stronger Green springs and followed the recommendations. All 6 magazines now function flawlessly. Thanks for solving these issues for me I particularly appreciate the replacement of one of the followers that broke during installation. Excellent product, excellent service!
