Hello,
Since you're new, here are few general truths about handguns, pistols or revolvers.
1. Perceived recoil is the combination of the caliber of the round, the mass of the handgun, and the total area of the contact patch between the hand and the handgun. In general, perceived recoil and pistol size are inversely proportionate. The bigger the gun, the less perceived recoil. The smaller the gun, the more perceived recoil.
2. A handgun provides one and sometimes two points of contact. Because of this, it presents aiming and trigger challenges. One of factors that comes into play is the distance between the rear sight and front sight, also known as sight radius. The length of the sight radius is inversely proportionate to the ease of aiming. The longer the sight radius, the easier it is to aim and achieve precision and accuracy as distance to target increases. The shorter the sight radius, the more challenging it is to aim and achieve precision and accuracy as distance to target increases.
3. Properly learning basic handgun marksmanship techniques and earning the skill to shoot any handgun, regardless of trigger, requires both time and purposeful intentional practice. Practice takes ammo. Ammo can be expensive.
4. The larger the caliber for a given size handgun, in general, the greater the energy, hence the greater perceived recoil. For new firearms enthusiasts experiencing recoil, the amount of recoil can actually hinder the development of basic handgun marksmanship techniques. New firearms enthusiasts develop a flinch, push, heel, poor trigger control which they then practice over and over, ingraining bad technique into habit. Habituated bad techniques take longer to unlearn and retrain than having learned the correct basics the first time.
Given these 4 general truths, this is why you are receiving the advice you have so far.
You might be better served by buying a full size pistol. The sight radius is longer, it has more overall mass, and the contact patch between your hand and the handgun's grip is increased. This combination makes for an overall more enjoyable shooting experience and learning experience. As a new firearms enthusiast, we want you to have a positive experience so that you continue in your firearms enthusiasm.
The suggestion for a .22lr, full size, semi-auto handgun comes from all the advantages above, but includes greatly reduced perceived recoil and decreased ammunition cost. Greatly reduced recoil allow you to focus on the basics of grip, stance, sight picture, trigger press. The relative affordability of .22lr ammunition allows you to have more trigger time. After you've learned and ingrained good handgun basic marksmanship fundamentals, move up to a center fire cartridge to learn recoil mitigation techniques. Good .22lr semi-auto pistols: S&W Victory, Ruger MK4, Browning Buckmark.
Welcome aboard, and I wish you all the best in your firearms enthusiast progression.
