I have been looking online for holsters and found that the BlackHawk CQC SERPA Holster for the P2022 will work for it but I wanted an IWB option. After looking around it is hard to find anything that says it will fit the rail for the MK25. Then I remembered I had a Kholster for a Beretta 92 that I was carrying my Bersa 9mm High Cap pistol in. Tried the P226 and it did not fit so I put it in the oven for 6 minutes at 300 degrees and voila, instant fit.
