I had no trouble hanging onto a 2nd Gen Model 27, and yours is only a 9mm.
So my tip is to not waste your money.
Unless, wait just a minute, your name.....
If you are a smaller handed person, I can understand wanting the best possible grip. There are slip-on rubber sleeves from both Hogue and now Pachmayr that do help here.
The Pachmayr ones are tailored for exact models of pistols so may be a little easier to get on.
Pachmayr sleeves
The Hogue ones can result in quite a tussle when you go to put them on, but they stay in place and have a slight palm-swell. I have them on a Kahr PW-9, on a S&W 3904 and a S&W 5906 and all are improved IMHO.
As for the fuzzy stick-on panels, I can't tell you anything. Best of luck.
