I just received new Stainless Guide Rods from Bigtaco for my Steyrs. I have used Stainless Guide Rods in my Glocks for years. I will be updating this post periodically as I have new information to add. First, some basic comparison photos: Business Ends of my Glock 17, Steyr M40-A1, Glock 19 - With Stainless Rods Installed: Here we have the Stainless Rods on the left, and the original Factory Rods on the right: Glock 19: Dead Bang Recoil Rod Glock 17: Haarts Recoil Rod Steyr M40-A1: Bigtaco Stainless Recoil Rod A little more personal: Relative comparison - installed, side view: [Haarts, Dead Bang, BigTaco, Original] All in all, I was very pleasantly surprised when I received Bigtaco's Stainless Rods today: They appear to be of the highest quality craftsmanship and materials. My Haarts Rod and Dead Bang Rod were substantially more expensive than Bigtaco's Rod, yet his is by far the most impressive when held and gazed upon. To be fair, the Haarts Rod and Dead Bang Rod are substantially more complicated to assemble, but neither offer the same exceptional appearance or feel of Bigtaco's Stainless Guide Rod. [IMHO] ...more photos and range report for all three of my Steyrs [M9 M9-A1 M40-A1] soon!!!
