I've been handgun shooting for 56 years. I bought an IWI Masada Slim last fall. After testing, it's become my daily carry. Two months ago, I bought a Masada Tactical for its 17rd capacity. Both have green dots and are superbly made, well-balanced, and accurate, plus noticeably lighter than my CZ 75B and compacts that I've carried for 20+ years.Welcome from Sparks, NV. I, too had the same problem when I got around to purchasing a .45 which I carried during the early 60's. However, when I went to my LGS, I found it to be too heavy.
The only addition I made to both was applying Talon Pro grip texture.
I also have an IWI Zion AR15 that's well-made. IWI makes outstanding guns with excellent value for the money.
