I never tried any Chips, I thought the wilsons were OK. I really liked the Tripp's. Felt like a lot better mag and never gave me any troubles, the wilsons bobbled once and I felt iffy after that about them.
Tripps are great from what I hear, but darn spendy. The Chips have never given me any problems and the Wilsons have only failed to lock open a couple of times. Once on my Ruger SR1911 and once on my Sig TacOps.
