These are just what you need if you convert your old-style Sig Sauer P250 to the new X-Grip. These will allow you to convert your old magazines. I verified that it works without a hitch.
Advantages: Allows you to convert your old-style P250 mags to the new X-Grip style if you change your grip to X-Grip.
Disadvantages: Should come in a multi-pack.
