Absolutely love my 4003TSW. Carried it on-duty for years and during all my practice and training shoots I never had any problems so I had 100% faith in the gun. Bought mine about 7-8 years ago and it came with blue followers. I've also acquired some yellows that have run fine. I have no preference on the colors. You'll love the gun it's a workhorse and a great shooter. I am slightly biased towards Smiths though.
