Two Sig Sauer P228 P229 22LR conversion magazines
SIG Sauer P228 / P229 .22LR Conversion Magazines — Set of 2
So you own the P228 or P229 .22LR conversion kit and found out it only ships with one magazine. This set solves that. Two genuine SIG Sauer P228/P229 .22LR conversion magazines, 10 rounds each. Factory original parts. These are genuinely scarce — not a walk-in-and-buy product at any dealer.
Two Sig Sauer P228 P229 22LR conversion magazines These are not 9mm P228/P229 magazines. First, .22LR conversion magazines are specific to the rimfire slide assembly and use different internal dimensions than the centerfire magazines. Next, the conversion kit itself installs in minutes with no tools, by simply swapping out the standard slide assembly. Finally, having two magazines turns the conversion kit from a single-mag novelty into an actual training tool.
Will these magazines work without the .22LR conversion kit?
No. So these Two Sig Sauer P228 P229 22LR conversion magazines are specifically designed for use with the P228/P229 .22LR rimfire conversion kit, not the standard centerfire slide assembly. Also, the .22LR magazine dimensions are different from the 9mm, .40, and .357 SIG P229 magazines — they are not interchangeable. Therefore, you must have the .22LR conversion kit already installed before these magazines have any function.
Why are these Two Sig Sauer P228 P229 22LR conversion magazines so hard to find?
Scarcity is real and documented. So the SIG P228/P229 .22LR conversion kit only ships with a single 10-round magazine, leaving owners immediately looking for spares. Also, SIG has not consistently kept these magazines in production, and demand from conversion kit owners consistently outpaces supply. Therefore, shooters have resorted to 3D-printed alternatives at $40 each just to run their conversion kits with more than one magazine.
What’s the capacity of these magazines?
Two Sig Sauer P228 P229 22LR conversion magazines 10 rounds of .22LR. So unlike the centerfire P229 magazines that hold 12-15 rounds depending on caliber, the .22LR conversion magazine holds 10 rounds of rimfire ammunition. Also, this is the standard factory capacity for this specific magazine — no aftermarket extended options exist for this platform. Therefore, running two magazines gives you 20 rounds of .22LR training capacity before you need to reload.
Do these Two Sig Sauer P228 P229 22LR conversion magazines fit the P226 .22LR conversion as well?
No. So SIG makes separate .22LR conversion kits and magazines for the P226 and the P228/P229. Also, the P226 uses a wider frame than the P228, and the base plates and magazine dimensions differ accordingly. Therefore, P226 .22LR magazines will not fit a P228/P229 conversion, and vice versa.
Who is this Two Sig Sauer P228 P229 22LR conversion magazines set best for?
This Two Sig Sauer P228 P229 22LR conversion magazines fits P228 and P229 owners running the .22LR conversion kit who are tired of stopping after every 10 rounds to reload. So if you’ve been dry-running your conversion with a single factory magazine, adding a second dramatically improves the training experience. Also good for anyone specifically looking to stock up while genuine SIG factory magazines are available, since availability is unpredictable.
