So what happens to your stock? Are you going to pin them? In the bulletin it states that these can become legal if they are pinned to 10. So why kill the orders when you can pin them and still ship them (I'm assuming).
Even though I don't have this firearm or mags this shouldn't fly. This is a rifle magazine and was designed as such. If Ruger introduces a pistol that takes these magazines at a later date, that shouldn't matter.
Maximum Permitted Magazine Capacity
Special Bulletin for Businesses No. 72
1. Magazines designed or manufactured for both rimfire calibre rifles and handguns
Magazines designed to contain rimfire cartridges and designed or manufactured for use in a rifle do not have a regulated capacity. However, magazines designed to contain rimfire cartridges and designed or manufactured for use in a semiautomatic handgun are limited to 10 cartridges. Magazines designed or manufactured for use in both rifles and semiautomatic handguns are subject to the handgun limit of 10 cartridges.
Example:
Smith & Wesson M&P 15-22 rifle and 15-22P pistol chambered for 22LR caliber:
the 10 round magazine is unregulated
the 25 round magazine is a prohibited device
Example 2*: The Ruger BX-25 magazine, chambered for 22 LR calibre, is designed and manufactured for use in the Ruger SR22 rifle, the 10/22 family of rifles/carbines and the 22 Charger handgun. As a result, this magazine is a prohibited device unless modified so its capacity is 10 cartridges or less.
