I'm considering buying a Sig P229 .40. Now, I carried a Sig P229 .40 as my service weapon for 6 months before my department switched to the Sig Pro 2340 .40. I really didn't shoot it that much maybe a total of 800 rounds through it before it was turned in. I was talked with a shooter who said that he owned a P229 in .40 and that he went through 4 frames after cracking the rails on them. He stated that when he got to about the 1,000 round mark is when the rails would crack. Anyone else have any problem with this??? Any help and/or advise would be most appreciated!!!
