If you were considering a new style of shoes, would you buy a cheap pair and base a buying decision on that? Cheap holsters are like cheap shoes. They are poorly constructed and uncomfortable.
The Sig229 is going for $600 - $700.00 dollars now. Why would you spend all that money on a nice gun and then buy a cheap holster?
Buy a good belt holster to start with. You can get into a good quality holster for around $100.00. It will be comfortable and if properly maintained give many years of comfortable service.
