I'm currently doing some serious thinking of getting a Sig 250 but have some concerns that maybe others don't have,how well do you think the conversion kits to other calibers are going to be fit wise? The whole purpose of me buying it would be the simplicity of it being modular to other calibers but I want to make sure there is a good fit, how can you be assured with these kits not even out yet,I've heard NH has had alot of QC problems also.Do you think or foresee these kits eventually coming down a little in price? $400.00 isn't far from the cost of another new pistol. I really wanted a Sig but all the feedback if been getting is for the same price I can get a CZ PO1 which is said to be more accurate and just as reliable, any feedback would be greatly appreciated to help me make a final decision.
