What model is that Sig in the picture, and how many rounds does it hold?
That is one of my SIG P226s. It has the Mecgar flush fit 18 round magazine in it.
The P229 is a little bit more compact and uses 15 round flush fit magazines in 9MM.
For about half the price you can get a SIG SP2022 which has a poly frame but is also a terrific pistol and holds 15 rounds. YES a SIG pistol for under $500!!
Here is one of my P229s and my SP2022.
