5 of 5 Excellent Service and Product !!! May 18, 2021
Reviewer: Ray E. from Reno, NV United States  
The Last round hold open follower works great with the stock 10 round plug in my P228/9 22lr conversion. You still have to lock the slide back manually before you pull the magazine. The slide goes forward otherwise... (Not an issue for me. Knowing I have an empty chamber is more important; especially If my wife is shooting the gun).  If you plan to use the 15 round option; Get their spring upgrade as well. It has higher compression. The stock spring works but I had more issues with feeding.
