I am also left handed and switched my mag release. BTW, good luck finding a QUALITY left handed holster for a P250. I am learning to shoot right handed now, as I should do anyway. If you decide to CC the 250 I reccomend a Pancake holster that sits up high. I have tried all other ways, IWB, shoulder, ect. The pancake works the best for me due to the size of the gun and my gut. If you do decide IWB, plan on buying new pants that are 1-2 sizes larger.
