Its not a safety. Its a de-cocker for when you are done firing with a still loaded gun. Then it makes perfect sense.
After break in and identifying a MIM mold fragment on the hammer face and removing it, my SR22P has functioned perfectly. It is easier to shoot than any DA revolver, recoil free, and hits where the sights are adjusted to. My 9 year old grand daughter can shoot it just fine. Any adult should be able to also.
The small back strap option makes it quite comfortable for small hands. But I with 2XL glove size shoot it just fine with the small grip.

Or even easier I guess: Copy/pasted below, but it deletes the pictures at the URL above. Note the ammo info. The SR22P runs on most anything, but does really well with CCI products.
_______________
For the novice shooter with a new pistol, there are a number of things that can be done to increase the ease of use of the new pistol. The steps likewise help insure future satisfaction and avoid problems. While not all inclusive, they would include:
1) Read the manual that comes with the firearm.
2) Strip the pistol, clean it, lubricate it, and re-assemble it. Some manufactures ship pistols dry of any lubricant and really need lubed to run without damage.
3) Discretely number the magazines that go with that pistol. Fingernail polish, electro-pencil numbers, or your own system. The reason is so that you can attribute any firing difficulty to a particular magazine or know it happens with all of them.
4) Take the pistol out and shoot it for function with different ammunitions. This is to break it in functionally and to settle the parts so that they can be zeroed and not wander off as they settle in later.
5) In this process, you can get a rough sighting in. Depending on the type of pistol, if it has an adjustable rear sight, center the rear sight. Then shoot the pistol and move the front sight left or right to adjust windage on the assumption the movement keeps it fairly near the center line of the slide. At the same time, you can adjust the elevation for vertical impact.
5a) In moving either the front or rear sight, how much to move it is always a headache. There are mathematical formulas down to the last 0.001". Easier is to use a 0.7mm mechanical pencil and put a pencil line on each side of the sight on the bottom of the dovetail cut into the slide. As you move the sight left or right, cover one line and expose the other line more. With a full size 4-5" barrel service pistol, one line is about 2" at 15 yards and 3" at 25 yards. With a smaller pistol having a 3-3.5" barrel, one line is about 3" at 15 yards or 5" at 25 yards. The difference is because of the sight radius being much shorter. The same amount of move generates a larger change in the smaller pistol. The line that you move away from is always there so you can move back towards it if you went too far. Degrease the dovetail bottom before marking and the pencil mark lasts a good while.
5b) If the pistol has a fixed front sight, then you can only move the rear for windage.
5c) If the pistol has a dovetailed front sight, or if you have changed the front sight for another style such as the HiViz, in this process is a good time to fix the location of the front sight so that it doesn’t decide to wander off in the future. You will avoid questions like, “Why is my gun shooting a foot to the left all of a sudden.” This is done easily with either or both of a super glue and Locktite. Locktite the screws as with this SR22 HiViz front sight and let super glue seep into all the cracks and crevices between the slide and sight. It will stay put, but yet come loose if needed. The glues work best if the sight and slide were degreased before any shooting.
5d) Please note that this sight information applies directly to the SR22P and may not apply to other pistols. It would depend on the nature of their sights, the sight material construction, and how tight the sights are in their dovetails. The factory front sight in the SR22P is very serviceable, but made of plastic and moves in the dovetail quite easily. The HiViz sight was snug, but easily moved in the dovetail with a brass drift. It needs the set screws tightened and Loctited. Other pistols like the Glocks have a fixed front sight and plastic-steel-night sight steel rear fixed and plastic adjustable sights depending on the model. They should be moved left and right only with a Glock sight tool.
6) The rear sight can be final fine tuned for this click left or that click right as need be. As the pistol is being carefully shot at this stage to set a zero, it might be bench rested or carefully fired offhand as shooting skills allow.
7) As the points of impact of different ammunitions are noted and recorded, along with accuracy, the new shooter will start to get an idea of where this or that ammo might be expected to impact.
8) If forced to use a different ammo than your “standard”, you will have a good idea of where something else will impact and not need to start all over again. This Ruger SR22 put:
-CCI MiniMag 40RN
-Remington 40RN (1964 Golden Bullets)
-Federal 40RN HS
-CCI Blazer 40RN
-American Eagle 40RN
into essentially the same zero at 15 yards. I haven't gotten to try the Velocitor or any standard velocity or hollow points yet. But you get the idea. The Magic Marker colors let you put 10 shot groups on the same target for quick reference and yet tell the shots apart. I still need to lower this rear sight probably one more click. As you shoot, try to get some idea of the amount of adjustment each rear sight click creates. It would be nice if the manufacturers listed the change rate.
9) Other ammo of note:
WW SuperX 36HP: same point of impact: good function
Remington Viper 36TCSB hyper velocity: same location and snappy action function.
9a) I have noticed that the Federal 40RN gives both erratic ignition and recoil impulse from more or less powder. Needing second strikes and rounds firing that do not operate the slide are tell-tales. Both affect accuracy which is poor. The AmEagle 40 RN is not much better, also a Federal product.
9b) The CCI products and especially the RemViper function with alacrity and you can tell they fired. The gun clearly likes snappy ammo.
