Wilson Flat Spring Kit on a RIA 1911 Problems



I purchased two Wilson Combat Flat Spring Kits for my RIA 1911 38 Super and my RIA 1911 45 Tactical.

The kit does not fit either RIA 1911's. It appears that the head of the guide rods are wider than the original guide rods heads (one standard and one FLGR).

I have not seen this problem on the web site but have review reports and video evidencing a no problem fit in various 1911 RIAs.

So, any suggestions for a correction or another product with a flat spring guide rod?
